Patent FR-2010837-A1 (FR)
Title: Carpets having an expanded polyurethane backing layer
IPC: C08G18/48
Filed: 1969-06-13
Abstract: Process for prepn. of a high pile carpet with an expanded plastics backing layer comprises spraying a liquid mixt. of polyurethane foam-forming materials onto the backing side of a high pile carpet, on which no backing layer is yet present, under such conditions that the liquid rapidly reacts to form a foam, which cannot appreciably penetrate through the basic fabric. The backing layer firmly anchors the loose pile loops in the base fabric, and improves the dimensional stability of the carpet. The spraying process enables the foamable mixt. to be uniformly applied, without any penetration of the basic fabric. The durability of the carpet is considerably prolonged.

Title: Luminescent screen mfe
IPC: H01J9/227
Filed: 1970-11-09
Abstract: Coloured or colour-emitting materials are applied to the surface of a glass or ceramic article by imagewise exposing the surface which carries a solid light sensitive organic layer capable of developing an Rd of 0.2-2.2 to actinic radiation, placing free flowing particles of 0.3 mu diameter of the coloured or colour-emitting material on the organic layer, (thickness 25x the organic layer) embedding the particles in the form of a monolayer in the surface of the organic layer while the surface of the article has a temp below the m.p of the particles, to produce an image with regions varying in density in proportion to the exposure of each region removing non-imbedded particles heating to red heat to remove all the organic material from the surface of the article, and to bond the particles to the surface of the article, and, before or after heating, coating a second layer of the same or another light sensitive organic material capable of developing an Rd of 0.2-2.2 with a thickness of at least 0.1 mu, and repeating the previous stages.

Title: D.C. Switching telecommunication type electronic switch - has rapid switching with short cct and over voltage protection
IPC: H03K17/082
Filed: 1973-02-22
Abstract: The switch has a number of inputs which receive signals to actuate the electronic cct. Protection of the cct. is assured by separating into two parts the control cct. of the control stage. The first part only permits passage of transient current destined to actuate switching. The second part only permits passage of the normal control stage supply current. In the case where the cct. output current does not exceed a certain value, feedback between the circuit output and the input of the control stage ensures blocking of the control stage in case of a fault in the output circuit.

Title: Plastic foam with high filler content - prepd. using non solvent component which swells plastic
IPC: C08J3/21
Filed: 1973-06-29
Abstract: A process for producing plastic materials contg. fillers and/or inexpanded form by adding fillers and/or gas to a soln of the plastic material, involves the use of a solvent comprising two or more liquids of which one is a good swelling agent but a non-solvent for the plastic. The liquid mixt. gives solns. of much lower viscosity than normally obtd. with the same plastic in the individual solvents. The process allows the incorporation of large amts. of fillers (e.g. up to 90 wt. %) into the plastic without mixing and extruding at high temps. but by simple manipulation of the polymsn. solns. Foam products of s.g. 0.01% than of the plastic used may also be obtd. by the process. The process is used specifically as a joint sealant by in-situ removal of solvent.

Title: Dishwasher with collecting chamber and filter sieves - has valve between two divisions of chamber preventing contamination by food residues
IPC: A47L15/42
Filed: 1975-10-07
Abstract: The dishwasher contains a collecting chamber (1) which incorporates filter sieves (4, 4') and a connector pipe (2) for the circulating pump and a connector pipe (3) for the detergent additive pump. The filter sieve (4) divides the collecting chamber (1) into an intake chamber (5) for the circulating pump and an intake chamber (6) for the detergent pump these two chambers being connected together by a valve which may be designed as a float valve (7) and allows fluid flow from the intake chamber (5) to the intake chamber (6) but not vice-versa.
